What is it you're trying to do? Delete roaming profiles?

Thanks
Alex

sorry, ive changed the title, that was an error.

Delete Local Profiles - folders in C:\Users etc.

Ok so only local profiles.

Get-WMIObject -class Win32_UserProfile | Where {(!$_.Special) -and ($_.ConvertToDateTime($_.LastUseTime) -lt (Get-Date).AddDays(-5))} | Remove-WmiObject

Select allOpen in new window

That'll do it, you'd be better off using group policy though

I do not have a test machine to run this against, but it seems like it will work.

I am using Alias (Shorthand)

GWMI -class Win32_UserProfile | ? {!$_.special -and $_.localpath -notmatch "administrator"} | Remove-WMIObject -whatif

Select allOpen in new window

OK trying:

Get-WMIObject -class Win32_UserProfile | Where {((!$_.Special) -and ($_.LocalPath -ne "C:\Users\Administrator.sls") -and ($_.LocalPath -ne "C:\Users\Administrator") -and ($_.LocalPath -ne "C:\Users\Public") -and ($_.LocalPath -ne "C:\Users\Default"))} | Remove-WMIObject

Select allOpen in new window

errors:

Are you running powershell as a admin?

OK, it now runs, no error and immediately returns to the powershell prompt. no folders get removed., there are 50 + to remove.

If you're having trouble with Remove-WmiObject, I would try the Delete() method.  This is what I've used in the past.

Get-WMIObject -class Win32_UserProfile |
 Where {((!$_.Special) -and ($_.LocalPath -ne "C:\Users\Administrator") -and ($_.LocalPath -ne "C:\Users\Public") -and ($_.LocalPath -ne "C:\Users\Default"))} |
 ForEach-Object { $_.Delete() }

Is this a terminal server?

No, these are win 10 workstations

Wow.  With 50+ profiles.

Profiles get created when a new user logs in. These are open access IT rooms in a school, potentially 1500 users.
